WALTHAM WATCHES. ™M.JS.I?i icltlng annw the Public patronage of WATCHES of domestic production, the AMERICAN WATCH COMPANY respectfully represent: That no fact in the history of manufactures is more completely demonstrated than that the best system of making Watches is the one nret established by them at Waltham. That system always had the warrant of reason and common sense, and now the test of time in the trial of the Watches themselves cannot be denied to have been ample and satisfactory. It is admitted on every hand—the evidence of daily observation and common reputethat the Watches not only keep correct time, but that as machines they ENDURE.

They confidently assert there is no longer any need for such reasons to import watches of any de-criptio...

THE EAGLE HAY PRESS. The above is a correct representation of this remnrkablo Eagle Hay Press, THE INVENTION OF J. A. McOILLIVRAL, OF ILLINOIS, TO WHOM LETTERS PATENT WERE ISSUED JANUARY 10TH, 18G5, AND JULY 24TH, 1866. Several years were devoted by the patentee to the perfection of this powerful press, and its unprecedented sale in the Enst induces the proprietors to introduce it into California and the Pacific Htates. All who have seen or used these Pressos pronounce them superior to anything used heretofore. The power is applied by means of two levers, and it will be seen the power increases in ratio to the resistance; as the levers approach a horizontal position the power can scarcely be estimated. It is not only a powerful Press, but has the advantage of being Cheap, and also Simple, therefore not liable to get out of order. Three men with one horse can bale from Ten to Fifteen Tons per Day, each bale weighing 250 to 300 lbs. It obviates all necessity by beating the hay before ...
